Ball and Spherical-Shell Rigidity from Overdetermined Translating Solitons
Liang Cheng, Li Ma
We study overdetermined boundary problems for the graphical translating-soliton equation \[ -\operatorname{div}\!\left(\frac{Du}{\sqrt{1+|Du|^2}}\right) =\frac{1}{\sqrt{1+|Du|^2}}…

On locally conformally flat manifolds with positive pinched Ricci curvature
Liang Cheng
By using the Yamabe flow, we prove that if , , is an -dimensional locally conformally flat complete Riemannian manifold , where is a unifo…
